Application filed August 28, 1919. Serial No. 320,518.

To all to 7mm it may concern Be it known that Josh DnLrrNo, a subject oithe King of Italy residing atBuenos Aires, Argentina, has inventedcertain new and useful Improvements in a Lubricating Hub for CircularPlow Knives, of which the following is a specification.

This invention relates to improvements in rolling colters for plows.

One of the objects of the invention'is to provide a rolling colter somounted on its supporting means that any earth gathered by the disc ofthe colter and falling upon the bearing of the device, will beloosenedand discharged without afl'ectingthe journal of said disc. l I

Another object of the present invention is to furnish a rolling colterhaving supporting means constructed to provide brackets to which acleaning device or scraper for the disc may be attached.

A further object ofthe present invention is to provide a rolling colterwith means for eiiectively lubricating the interior of the disc hub. i

With the foregoing objects outlined and with other objects in view whichwill appear as the description proceeds, the invention consists in thenovel features hereina'tter described in detaiL'illustrated in theaccompanying drawings and more particle larly pointed out in theappended claim.

Referring to the drawings Figure 1 is a side view of my improved colterand supporting mechanism.

Fig. 2 is a top plan view of the same.

Fig. 3 is a sectional view.

In the drawings, A designates the colter disc which in the presentinstance is connected at its central portion to a hub formed ofsubstantially identical hub rings 13 each of which is provided with aconical shaped periphery, the smaller end of whieh'is arranged at theouterend of the hub ring. This conical shape of the hub rings causes anyearth carried by the disc and falling upon the hub to be guidedoutwardly away from the disc A.

The disc and hub rings are rotatably mounted on an axle D provided witha transverse slot C which receives lubricant from a lubricating cup Jwhich is arranged at one end of the-axle. By this construction,lubricant placed in the cup J will feed axially to the slot C and willthen travel transversely through said slot to the periphery of the axle.The interior of the hub is provided with a bearing sleeve H which hasslots designed to permit oil from the slot C to pnipr the hub andeffectively lubricate said 111 The ends of the axle D are mounted inside bars G, which have their upper ends resting in recesses in thetines P of a fork O. and bolts R secure the side bars to said tines. Thefork O is provided with a socket through which the crank-sl1aped lowerend L of the support extends and a securing member M prevents said forkfrom leaving the part L. I

The axle D is provided with two fixed collars E which are arrangedbetween the side bars G andithe hub rings B, and the inner ends of thesesleeves are located in internal annular sockets provided in the outerendsof the hub rings B. By this construction any. earth falling on thehub rings c ude.

B will be thrown outwardly upon the sleeves V E and will fall from thesesleeves to the ground. The arrangement of the conical faces of the ringsB and the overlapping of f the ends of the rings and the sleeves E inthe manner shown and described, will ct :Fectively dischargethe earthgathered by the disc Awithout permitting the same to enter the interioroi" the hub. Hence the machine or plow provided with the improvedrolling colter will have a longer life than plows employing the coltersnow in general use. as the bearing of the present colter will remainunaffected by dampness or dirt which would be liable to enter the hub,The lower ends of the arms G are extended and apertured as shown at K inorder to provide supports to which a cleaning knife or scraper for thedisc may be attached.

While the preferred embodiment of the invention is illustrated in thedrawing, it is apparent that various changes may be made in theconstruction shown without departing from the spiritof the invention asdisclosed by the claim.

What I claim and desire to secure by Letters-Patent is: i r

A. device of the kind described including a support having side bars anaxle connecting said side bars and provided with two spaced cylindricalsleeves, a member rotaternal shoulders which engage the inner ends ofsaid sleeves, said member being provided extending 'throughthe axle forfurnishing With internal annular cylindrical sockets into lubricant t0thfi Slotted Sleeve- 10 which the inner ends of said sleeves extend, Intestlmony whereofl afiix my slgnatul'e a slotted cylindricalslee'vemounted 'on said 1n Presence Oftwo. Wltnessesaxle and spacing the firstmentioned sleeves O DELFINO- epart, said sllott-ed sleeves being of lessWitnesses: thickness than the other sleeves and form- MAYER, ing a;support for the member, and means a S.
